Water dispenser slow / trickles
Always start with the filter. PureSource filters clog gradually — flow drops 50% by month 5.
Diagnostic flow
- 1
Replace the water filter
PureSource Ultra II (EPTWFU01). Twist the cartridge 1/4 turn and pull. Flush 2 gallons through the new filter.

Bypass test
If flow is still poor with a new filter, install the bypass plug. Strong flow = bad filter batch; weak flow = inlet valve or supply line.
- 3
Check the saddle valve
Behind the fridge, fully open the shut-off. Old saddle valves restrict flow when partially open.
- 4
Test the inlet valve
120 VAC at the valve when dispensing; <40 PSI inlet pressure = valve. Replace 242252702.
